Outcome measures. (A) Bar graph comparing mean QuickDASH scores at initial presentation and in follow-up after surgical treatment. Comparisons were made using the paired student t-test. (B) Bar graph comparing the percent improvement in QuickDASH scores for different patient-reported outcome (Derkash score) groups for patients undergoing SCD + PMT and isolated PMT. (C) Bar graph comparing the percent improvement in QuickDASH scores for patients who did or did not have a previous ASM and/or PMM block with local anesthetic prior to undergoing SCD + PMT or isolated PMT.

ASM, anterior scalene muscle; F/U, follow-up; Neg, negative; NS, not significant (P > .05, unpaired student t-test); PMM, pectoralis minor muscle; PMT, pectoralis minor tenotomy; Pos, positive; QuickDASH, 11-item version of the Disabilities of the Arm, Shoulder, and Hand survey; SCD, supraclavicular decompression.
